Why
integral? The answer is here.
The primaeval definition of a virgin which denotes a person who has not had sexual
intercourse
preserves its exact meaning in the current medical - legal dictionaries.
A virgin does NOT denote a young woman (a girl):

The
first person described as a virgin till marriage was Rebecca.
She is important for the majority of people living on Earth.

As
of the early twenty-first century, it was estimated that 54% of the
world's population (3.8 billion people) considered themselves adherents
of the Abrahamic religions, the monotheistic faiths emphasizing and
tracing their common origin to Abraham. The
only son Abraham had with his wife Sarah, was Isaac ( יִצְחָק,
Ἰσαάκ, إسحاق), and Isaac's wife was Rebecca aka Rebekah who
was
the first virgin mentioned in the Bible, as early as in "The
Book
of Genesis", Genesis 24:16:
She was very pretty. She was a
virgin; no man had ever had sexual relations with her. She went down to
the well and filled her jar. Easy-to-Read
